Abstract

A new dimer polyoxoniobate [Cu(en)(2)](11)K(4)Na(2)[KNb(24)O(72)H(9)](2)·120H(2)O (1) has been synthesized and systematically characterized. Visible light photocatalytic H(2) evolution activity was researched with 1 as the visible-light photosensitizer and catalyst, cobaloximes [Co(III)(dmgH)(2)pyCl] as the co-catalysts, and triethylamine (TEA) as the sacrificial electron donor.
